BackgroundConsidering articular distal radius fractures treated with volar plate, we hypothesized that articular radio-carpal displacement was better reduced with arthroscopic control than with only fluoroscopic control.MethodsForty patients with similar articular radius fracture (type C according to AO classification) and high functional needs were treated with volar plate fixation. They were divided in two comparative groups: 20 patients in Fluoroscopic group and 20 patients in Arthroscopic group. Pre and postoperative radiographs and tomodensitometric images were analysed by an independent observer. We evaluate extra and intra-articular displacements according to "Patient Accident Fracture" classification.ResultsWe observed a better reduction of the radio-carpal step-off and gap in the arthroscopic group, with a statistically significant difference (p<0.05). The index of postoperative intra-articular reduction was better in the fluoroscopic group (5.5) than in the arthroscopic group (2.2) with a significant difference (p<0.05).ConclusionsAccording to these results, arthroscopy is useful to perform a better articular radio-carpal reduction in distal radius fracture.Level Of EvidenceLevel 3.Copyright © 2017.
